16. Model with Math At a drive-through restaurant,
Casey's family ordered a small drink and m medium
drinks. Anika's family ordered m medium drinks and
a large drink. Write an algebraic expression that
shows the total cost, in dollars, of both orders.
1.10+1.25m +1.50 +1.25m=
250m+2.605.1
17. Use Structure Combine like terms to write
an expression that is equivalent to the
expression you wrote in Exercise 16.
